In the RC candidates and the CE available via GitHud app/code/magento pool is included. In the distro from magento's website the pool is missing, where is the pool stored? I ask because I am getting messages saying that the Massgenerator does not exist:
a:4:{i:0;s:72:"Class Magento\Salesrule\Model\Coupon\MassgeneratorFactory does not exist";i:1;s:13600:"#0 /chroot/home/html/mag2a/vendor/magento/framework/ObjectManager/Definition/Runtime.php(44):
However the exact same code run on the CE distro containing the code/magento pool handles the code just fine.
